Semi-rigid Epoxy Joint Fillers

Semi-rigid epoxy joint fillers are a two component, self-leveling sealant for load bearing saw cuts or preformed control joints. This system supports the joint edges and reduces spalling of the edges caused by wheel traffic.

Where to Use

  • Concrete construction & control joint
  • Crack filler repair for old floors
  • Industrial and commercial floors
  • Interior applications


  • Tough performance, reduces floor joint repairs and maintenance.
  • Suitable for filling cracks in older floors to reduce the rate of deterioration.
  • Semi-rigid to formula that allows for limited temperature and humidity movement of concrete.

Urethane/Polyurethane Joint Fillers

Urethane/polyurethane joint fillers are a two component, elastomeric system designed for cracks subjected to movements. The system is available in self-leveling or non-sag application. Wide choice of colours.

Where to Use

  • Concrete construction & control joints
  • Window perimeters
  • Interior and exterior application
  • Ideal for vehicle traffic joints


  • High elasticity with a tough, durable, flexible consistency
  • Exceptional adhesion to most substrates without priming
  • Remains adhesively and cohesively bonded during temperature cyclic movement

Polyurea Joint Fillers

Polyurea joint fillers is a technologically advanced two component, quick setting, semi-rigid, solvent free, self levelling joint filler.

Where to Use

  • Recommended for use as filler for interior, horizontal saw cuts or preformed control and leveling control joints
  • Typically installed in facilities such as warehouses and industrial plants, where such joints are subject to load bearing conditions involving wear and impact
  • Also used for repairing interior concrete slabs that have experienced random cracking due to shrinkage


  • Quick set formula reduces down time
  • Cures at temperatures down to -25°C
  • Hard, load bearing filler designed to withstand industrial traffic
  • Provides even load transfer across floor joints, thereby protecting joint edges from breaking down under traffic
  • Improved moisture sensitivity
  • Low modulus of elasticity

Surface Preparation | East Coast Coatings

We use technologically advanced dust-free shot blast equipment, dust-free grinders, scarifiers and scrubbers to prepare your substrate to receive your new flooring system. Shot blasting is a method used on concrete and steel surfaces which prepares the surface for the application of a coating, seamless floor or any type of overlays.


Sealers, Liquid Hardners & Dustproofers

Sodium silicate based sealers are a propietary blend of Silconate polymers which penetrate concrete surfaces providing an increase in abrasion resistance and a reduction in the surface absorption of liquids. Silane/Siloxane sealers are a deep penetrating liquid designed to protect concrete structures, decks, and surfaces agianst the adverse effects of deicing salts, moisture, weathering and freeze damage.


Decorative Floors | East Coast Coatings

Designers and builders are drawn to stained concrete because of the unique outcome that can be achieved combining color and application techniques on concrete slabs. Versatile application where we incorporate vinyl flake chips and epoxy to create a decorative floor finish that is easy to clean and is resistant to chemicals.

Our crews and equipment are fully mobile, allowing us to service you anywhere in Atlantic Canada. Benefit from our outstanding service and long list of comprehensive extras.


Seamless Floors | East Coast Coatings

This troweled system produces an aesthetic and sealed seamless floor composed of multi-colored hard granular aggregates and is finished with a transparent topcoat which is available in gloss. A seamless Floor with a integral cove base is by far, the preferred method for ease of maintenance of floor and highly recommended by environmental health code.


Concrete Repair & Restoration | East Coast Coatings

Fiber-reinforced repair mortars are one component, shrinkage-compensated, superplasticising admixture enhanced with silica fume to offer high strength and superior performance for structural concrete repair. Polyurethanes injection systems are a two component, 100% solid, flexible polyurethane grout used to firmly bond to concrete surface, and will displace and stop water infiltrations.


Specialty Coatings | East Coast Coatings

The system is applied with a epoxy primer, electrodes made of copper are installed on the edge and between the control joints to insure the conductivity, conductive coat is installed followed by a chemical resistant top coat. A floor can be 100% completed overnight; including all surface preparation and the installation of multiple MMA coats.
